No handlers found: "torchvision::roi_align". Skipped

[padeirocarlos]

Thank you for your great work!
I encountered this warning when using torchprofile. It seems like torchprofile cannot calculate the MACs of

UserWarning: No handlers found: "torchvision::roi_align". Skipped
UserWarning: No handlers found: "aten::sqrt". Skipped
UserWarning: No handlers found: "aten::log2". Skipped
UserWarning: No handlers found: "aten::reciprocal". Skipped.
UserWarning: No handlers found: "aten::scalarimplicit". Skipped.
UserWarning: No handlers found: "aten::max". Skipped.

By the way, apart from the MACs, Is there any way to calculate the model memory use?

Thanks for reporting this issue. Most of these operators have no MACs or very few MACs, so the MACs should be roughly correct. I will work on supporting these operators.

Hi,
I met a similar warning when profiling my customized model wich contains of custom layers with some operators like permute, reshape and einsum.
Here's the log:

I guess it doesn't affect the final result. Just mentioning.
Thanks!
